Traccia
A frame is a set of angles argued from one rider and one road.
Traccia is one steel-frame bench in Edolo, under the Mortirolo, that treats a road as a specification document. Twelve kilometres at ten and a half per cent is not scenery — it is the gradient that decides the gearing, and the gearing that decides the chainstay.
The premise
The road writes the specification. The bench only executes it.
Bespoke framebuilding usually sells taste: the builder's eye, the house look, a lugwork signature. Traccia removes taste from the argument and replaces it with inputs. Height, inseam, rider weight, the road, and how long you want the front end — five numbers, two of which are about you.
Change any one and the drawing is redrawn: angles, trail, wheelbase, weight and price move together, because on a bicycle they were never separate decisions. What the builder contributes is knowing which way each one has to move.
Product principles
The world becomes a working system.
01 · Input
A road is a document, not a mood.
Two hours of braking on a wet hairpin decides which steel goes in the down tube. A descent that long decides how much trail the fork needs before the front end holds a line at seventy. None of that is preference.
02 · Measurement
Rider weight picks the wall thickness.
A rider at 58 kg gets 0,7–0,4–0,7 and a frame under 1 600 g. A rider at 96 kg gets 0,9–0,6–0,9 and is told the frame is 250 g heavier, because the alternative goes soft under him in three years.
03 · Limit
The shop says what it cannot do.
No titanium and no carbon — not as a position, but because he never learned to, and says so rather than inventing a reason. Paint happens down the valley in Brescia, and the site does not pretend otherwise.
Built proof
A concept carried into code.
Worldbuilding · Geometry configurator · Editorial commerce
- La valle
- The Mortirolo stated as a specification: twelve kilometres, ten and a half per cent average, eighteen at its worst, and every frame ridden up it unpainted before it ships.
- L'acciaio
- Butted tube walls explained as a manufacturing argument — thick where the heat and load are, four tenths of a millimetre where neither is.
- La traccia
- The signature. Five inputs redraw one frame to scale, with head and seat angle, trail, wheelbase, stack, reach, tube set and price recomputed together.
- La commissione
- The order carries the drawing the visitor made. One reply comes back with what he would change and why, and that reply is where the frame actually begins.
